ABSTRACT:
A reinforcing panel for a rectangular tubular carton for large size granular products is provided by forming the carton blank with a reinforcing panel hingedly connected to one end of the carton blank. The reinforcing panel is folded first, over a flat blade, and the free end thereof is glued to one of the wider carton walls and then a sharp section of the flat blade is used to part the hinged end of the reinforcing panel from the carton blank, so that the hinged end can later be glued to the other one of the wider walls, as the carton blank is erected in the usual way.
